Question 1003160: The price per unit, p and the demand x, for a particular material are related by the linear equation p=40-2/5x, while the supply is given by the linear equation p= 2/5x. At what value of p does supply equal demand?

From p=40-2/5x and p= 2/5x we can set them equal and get
40 - (2/5)x = (2/5)x
40 = (4/5)x
x = 50
Then
p = (2/5)x = (2/5)(50) = 20
